REMOVABLE sito COVER.

Application filed March 17, 1922. Serial N0. 544,549.

. provide a device ofthe above character which when in place on the top of the silo will be held securely against dislodgment by reason of its own peculiar construction and ywhich at the same time may be quickly removed and manipulated by the operator dur-` ing the filling of the silo.

Various other objects and advantages of my invention will become apparent during the continuance of the following description. f,

In the drawings:

Figure 1 is a view in side elevation of the top portion of a silo with my improved top or cover in position thereon.

Figure 2 is a view in bottom plan of the top or cover.

Figure 3 is a view in perspective of the skeleton frame of the top or cover.

The skeleton frame of the top or cover consists of body members and 11 whose vintermediate portion is cut away as at 12 so that vthey may be brought into interlocking relation as clearly shown in Figure 3. When in position a pin 13 may be inserted through the interlocking parts so as to retain the members in rigid relation to each other. Between the free ends of the members 10 and 11 are arranged curved stays 14 which complete the frame.

`Upon reference to Figure 3 it will be observed that the members 10 and 11 taper toward their end portions from a comparatively thick intermediate portion so that both their upper and lower edges 15 and 16 respectively are convex in shape. The end portions of body members 10 and 11 are cut away to form vertical shoulders as at 16 and horizontal shoulders as at 17 while at one end the body member 10 carries a trunnion 18 and at the other end a catch 19, for the bolt of a suitable `lock 19.

In order to complete the top or cover, the top of the frame is equippedv withfa series of cover boards as shown at 20. It is to be c understood of course that I am not limited to practical form.

VVhenin place at the top of a silo such as designated by the numeral 21 the shoulders of the members 10 and 11-rest on merely illustrates a the top and within the walls of the silo.y

An opening 27 is provided into which the trunnion 18 fits while the intermediateportion of the members depends within the saine as clearly shown in Figurey 1. positioned that the lock may be properly adjusted the sliding of the cover on the top of the silo or the accidental displacement thereof will be prevented but at the same time will enable an operator to manipulate the cover more freely once it has been dislodged. It is also pointed out that a cable 23 may i be attached to the top or cover as at 24 so that when the cover is dislodged it may be 4rice.v 'i y v this particular formof covering and that .the present embodiment suspended along the side of the silo from Vthe stud 25. -lWhat Vis claimed is:`

1. A top for siloscomprising a frame of double convex construction, and a cover por- -tion on said frame substantially as described.

2. A top for siloscomprising aframe con# i sistingof interlocking body members, the upper and Alower edges of said body inembers tapering from, 'a point intermediate the ends thereof to the outer ends of said member thereby providing al substantially double. convex constructiomstays arranged between the ends of said body members,'a cover po'rtion for said frame, and means to lock said top in position, substantially as described. l In testimony whereof I affix my signature in lpresence of two witnesses.
